Title: Improved process for refining light hydrocarbons especially petrol
IPC: C10G29/16
Filed: 1929-05-31
Abstract: 335,885. Scott, R., and Imperial Chemical Industries, Ltd. May 31, 1929. Purifying mineral oils. - Light hydrocarbons. produced by the destructive hydrogenation of oil, coal &c. are purified by passing them, whilst still in the vapour state and under a pressure of at least 10 atmospheres, through a solid purifying agent such as bauxite or fuller's earth. The process is particularly applicable to the purification of petrol obtained by the destructive hydrogenation of oils produced by the destructive hydrogenation of solid materials. Vapours so produced are freed from heavy oils by a hot catchpot, maintained at say 300‹ C., and while still under pressure are passed by a tube, 3 through bauxite contained in purifying chambers 1, 2 adapted to be used alternately. When the. chamber 1 is used for purifying, valves 4, 6 are open and valves 7, 12, 14, are closed, the purified vapours leaving by a pipe 5. Regeneration of the material in the chamber 2 is effected by passing air at 400-500‹ C. through the chamber, the air entering at pipe 9 and leaving by the pipes 11. valves 10, 13 being open and valves 7, 8, 14 shut. In an example, middle, oil boiling between 200‹ and 300‹ C., obtained by liquid phase destructive hydrogenation of a mixture of coal and heavy oil. is vaporized in a current of hydrogen and passed over a catalyst consisting of tin plate at 500‹ C. at a pressure of 30 atmospheres. The vapours, after passing through a. catch-pot maintained at 300‹ C., are passed without cooling through a bed of bauxite and the purifiedvapours condensed, the residual hydrogen being collected for further use. The condensate is fractionated and the portion boiling up to 170‹ C. separated for use as a motor fuel. Specifications 7282/14. 138,046, 205,868; 208,569, [Class 32, Distilling &c.], and 222,481 are referred to.

Labels are taken from a stack 15, Fig. 1, by means of a pick-up member 13 pivoted at 14 and comprising two spaced arms 19 which are gummed by rollers 18, Figs. 2, 7, during the upward swing of the member 13 towards the stack, the member then returning to a vertical position with a label extending across the arms 19. A suction transfer pusher 16 pivoted at 17 then swings about the pivot to pass between the arms 19 and make contact with the ungummed portion of the label to bring the label 21, Fig. 5, into contact with one face 22 of a suction delivery member 9 oscillatable about a vertical axis to bring two vertical faces 22, 23 alternately and respectively into positions of rest alongside and away from the path of bottles 2 fed on a conveyer 3. The label 21 is transferred to the face 22 which is remote from the conveyer 3, the delivery member 9 then swing- ing through 180 degrees to bring this face alongside the conveyer carrying the bottles one of which is then rolled by means of endless bands 10 over the label on the face 22. In the meantime, in another sequence of operations, the face 23 has received another label and oscillation of the member 9 brings this face alongside the conveyer for application of the label to the next bottle. A mechanical detector arm 41, Fig. 19 (not shown), or an electric switch controlling a solenoid may be interposed in the feed path to ensure that in the absence of a bottle, the arms 19 do not reach the stack 15 and do not extract a label. The gumming rollers 18 are carried by an arm 24 oscillatable between a gum roller in a trough and a position in the path of the pick-up member. A dating mechanism is operated by the sweep of the arm 24. Selected characters 127, Fig. 21, are carried on a lever 126 which is swung towards the stack 15 as the arm 24 swings to the right to print the date on each label before it is removed from the stack. As the arm 24 swings to the left, the lever 126 swings to press the characters 127 to an ink pad 128. The oscillatory movements of the several mechanisms are all commonly driven from a main shaft by simple cam, lever and link connections. Specification 624,246 is referred to.

[Class 38 (iii)] Travelling to predetermined limits.-An A.C. motor operating, for example, the feed motion of a machine tool through definite predetermined amounts, is brought to rest in the desired position by magnetic locking between the poles of the motor and stator. Upon closure of a switch X, contactor ST is closed to connect the motor stator to the supply, and an interlock switch of the contactor ST completes the circuit of contactor SC, which connects through resistance R, the rotor winding of the motor. The motor runs and operates, either directly or through gearing, a drum switch MNOP which, when it reaches positions intermediate positions 2 and 3, 4 and 5, or 8 and 1, depending on the setting of a master switch to positions “, ¢, or 1, interrupts the circuit of contactor SC and completes that of a self-maintaining contactor LK and his contactor connects the rotor winding to the supply and the stator and rotor poles are pulled into and maintained in line, the switch MNOP resting in positions 3, 5, or 1. Upon opening of the switch X all contactors drop out, and upon reclosing a similar cycle of operation takes place. In a simplified arrangement the resistances R are permanently connected to the rotor windings. In order that variations of load shall not cause the motor to pass a desired stopping position, a drag brake may be provided, and the motor arranged to give an excessive torque. Further, two contactors may be provided performing the function of the single contactor SC, operating alternatively, and mechanically interlocked with the contactor LK.
